Please welcome to the stage a master illusionist. An energy beam that stabs out of galaxy M87 like a toothpick in a cocktail olive is pulling off the ultimate magic trick: seeming to move faster than the speed of light.

Almost five times faster, in fact, as measured by the Hubble Space Telescope. This feat was first observed in 1995 in galaxy M87, and has been seen in many other galaxies since. It might have you questioning your entire reality. Nothing can break the cosmic speed limit, right? You can’t just flaunt the laws of physics… can you?

Awesome talk from the 33c3 last year about Dark Matter and Gravitational Waves.



Thanks! Will check out.

Plumes of gas erupting out of Enceladus — a small moon with an ocean of liquid water beneath its icy crust — contain hydrogen. Scientists infer a lot from that: that there are hydrothermal chemical reactions similar to those that occur at hot fissures at the ocean bottoms on Earth.

On Earth at least, hydrothermal vents thrive with microbial life, offering up the potential that icy moons far from Earth — called “ocean worlds” by NASA — could be habitable.
